Sustainable Construction with PA Entreprenør | Ditio
PA Entreprenør has spent over 30 years establishing itself as one of Norway’s leading contractors in sustainable building and construction. With deep roots in Oslo and an unwavering commitment to zero-emission operations, the company has built a professional environment and technical expertise that few can match. Their project at Bogstad in Oslo is a striking example of what the future of construction looks like — and how the right digital tools make it possible to manage at scale.
The company holds triple ISO certification in quality, environmental management, and occupational health and safety, reflecting a serious and sustained commitment to responsible construction. At Bogstad, PA Entreprenør is pushing that commitment further: with an all-electric equipment park and a zero-emission share exceeding 90%, the project positions the company as a market leader in emission-free construction sites in Norway.
Improved air quality and working conditions with electric equipment in the tunnel
The Bogstad project involves providing Voksenkollen and Holmenkollen with a two-way water supply. The scope is substantial — a 700-meter-long tunnel and a 400-meter shaft that together create a ring line from Bogstad up to Voksenkollen.
Project manager Jøran Jørgensen is visibly proud of how the team has approached the challenge. “By driving a 700-meter-long tunnel and drilling a 400-meter shaft, we are able to create a ring line from Bogstad up to Voksenkollen,” he explains, before describing a modification that captures the project’s innovative spirit. “The tunnel rig is a common Atlas Copco E2, which normally has a diesel engine. We have removed it and installed a hydraulic motor that runs on electricity.”
Electric machines
With extensive experience in traditional tunnel work, Jørgensen notes a tangible difference: the electric equipment significantly improves air quality and working conditions inside the tunnel. For crews spending long hours underground, that is not a minor detail — it is a fundamental improvement in their daily working environment.
”Every day, 350-400 tons of mass are transported from Bogstad”
Tunnel projects generate enormous volumes of excavated material, and managing that mass transport efficiently is critical. This is where Jørgensen sees the greatest value from Ditio Flow.
“The main gain with Ditio is that you get a very good follow-up among other things on the number of loads that go out of the tunnel, in addition to getting all data in real time,” Jørgensen says. The platform’s mass transport tracking is detailed down to the individual load — each one is registered, showing where the mass was loaded, where it is headed, who loaded it, and who received it. With real-time tracking, the entire logistics chain is visible as it happens.
“Every day, 350-400 tons are transported here from Bogstad. Therefore, it is crucial for us to have a system that works,” says Jørgensen.
Ditio increases motivation for documentation
As a project manager overseeing multiple active projects, Jørgensen depends on having clear visibility into what is happening on site. He highlights how Ditio Core has changed documentation habits among his teams — particularly through its photo-based reporting capabilities.
“We notice that a lot more pictures are coming out than before, and that employees have greater motivation to document. It’s almost like a Facebook feed,” he says with a laugh. For managers and coordinators working from the office, this steady stream of visual updates provides a real sense of the “temperature” at the construction site — a level of insight that traditional reporting methods rarely deliver.

Beyond documentation, Jørgensen points to the platform’s work processes and work order functionality as a meaningful step up for quality assurance. “The way Ditio visualizes key data and information means that we get an incredibly detailed cost picture of the various operations,” he explains.
Jørgensen wraps up with praise for the Ditio team’s responsiveness, noting — with a characteristic twinkle in his eye — that no product is ever truly finished. “They are very quick to implement all the minor adjustments that need to be made for the product to continually evolve,” he concludes.
